APPARATUS FOR DRAWING AND PRESERVING BEER.

SPECIFICATION forming part of Letters Patent No. 635,514, dated October24, 1899.

Application filed November 1, 1893. Serial No. 489,775. (No moclehl Toall whont it may concern: Be it known that I, THEODOR SCHNUTZ, ofHanover, in the German Empire, have invented new and useful Improvementsin ApparatusforDrawing and Preserving Beer,of which thefollowingisaspecification,referencebeing had therein to the accompanyingdrawings.

Figure 1 represents a detail vertical sectional view of so much of oneembodiment of myinvention as is necessary to illustrate the invention.Figs. 2, 3, 4, 5, 6, and 'Z are detail views, partly in section, ashereinafter more fully referred to, and showing means for automaticallycontrolling the regulation of the liquid refrigerant. Fig. 8 is a viewsimilar to Fig. l, but showing the preferred and complete system.

In Fig. 1, k is the tap-box, provided with isolating material 1'. Thisbox contains the conducting-tube Z, leading from the cellar. At itsnarrower lower portion 7a is closed by a plate I. it is arefrigerating-box standing upon it and filled with Water and pieces ofice. The refrigerative water enters through the sieve-opening 0 and runsinto the refrigeration vessel 7.2 (situated in the cellar and providedwith double walls and large coolingsurfaces,) where it fills the cooledhollow space H. At 0 the water enters the refrigerative coil and fromthis at 0 passes into the tap-box 70, from where it flows out at 0through the overflow-tube Z 1 The refriger ating-box k is made ofgalvanized-iron sheet. The refrigerative coil is built over with aperforated projection-bridge a, so that the pieces of ice which are putinto the inner space cannot damage the coil. with let-off cock h for theice-water,'is provided. By means of the cock 72, the Waterinflux for therefrigeration-box can be regulated. If during the winter it shouldhappen that the temperature of the cellar were lower than desired, thesame can easily be brought to the desirable temperature by means of asmall flame. To likewise impart this temperature to the water whichsurrounds the conducting-tube Z, the flame is placed under therefrigerating vesselk to the bottom of which for this purpose a smallprotectionplate 19 is riveted or soldered. This arrange ment has thefollowing advantages: that it is regulatable, cooling or refrigeratingthe tap- At 0 a let-off tube l boxandconducting-tubes and simultaneouslyrefrigerating or warming the cellar (which is air-tight and protected bysome non-conducting material) and the ice-container This arrangement canbe applied everywhere, and therefore is of particular value, since it isentirely independent of a water-main.

In Fig. 2 an automatic cooling arrangement is shown. 70 is a tap-boxprovided with isolating material and containing the conducting-tube Z,which extends into the cellar. k is a cooling-box resting upon it andfilled with water and pieces of ice. The refrigeratingwater entersthrough the opening 0 and proceeds into the tap-box 70 when the piston uis in the position shown in Fig. 3. When, by means of the influx of therefrigerating-water into the tap-box 7a, which at o is provided with theoverflow-tube Z, a certain temperaturesay 9 centigradeis attained, thehighlyexpansive gas in the balloon B contracts to such an extent thatthe position of the mercury q becomes such as indicated in Fig. 2, withthe result that the refrigerating-water influx is shut off by the upperportion of the piston u. The downward movement of the piston to iseffected by the spiral spring w. The mercury is adjusted according tothe height of the desired temperatures.

In Fig. 6 another construction of the automatic regulator is given. 22is a valve situated in the refrigeration-box 7a, which valve during theopening is kept in a certain position by the three bent rods '0 so thatthe water of the box 70 flows into the tap-box at 0 a strainer n beingprovided to protect the valve r. The lever 12 is not joined to thevalve, but balances it merely upon its extreme end. When the temperaturein B has attained a certain height, the valve Q) opens for a sufficienttime until the desired temperature-say 9 centigradehas been reached. Thedownward movement of the piston to, which causes the closing of thevalve '0, is effected by the spiral spring w. Fig. 7 shows the sameprinciple with ball-valve.

In Fig. 4 the refrigerating-Water enters through the sieve-opening intothe globular portion of the tube Z The lateral tube Z leading into thetap-box, terminates in Z. Below the globular portion the tube Z, on theone hand, terminates into the branch tube Z whereas, on the other hand,it continues downward and by means of a U-shaped bend is joined to theballB. Atanormal temperature for the tapping and drawing of the beersay9 centigradethe mercury standsin the position shown in Fig. 5. Inconsequence of this position of the mercury the refrigeratingwaterentering at o flows off continuously through Z and can be utilized forother purposesfor instance, for washing glasses, the. If, however, thewater in 7; becomes too warm, 1 will assume the position as in Fig. 4C.The efllux through Z is then closed, which causes therefrigerating-water to run through Z into the tap-box. This influxprevails until the water of the tap-box has attained that temperature atwhich the mercury assumes the position shown in Fig. 5. The waterentering at 0 will then again flow off through Z The overflow-tube Z'insures a constant level.

Fig. 8 shows an arrangement in which the automatic refrigeration of thetap-box is effected simultaneously with the cooling of the cellar. Thedrawing will be understood without further comment.

As will easily be seen, the most varied arran gements may be chosen forsuch water and ice refrigeration, which, however, are all based upon thecommon principle torefrigerate in a regulatable manner upon the wholelength of the course of the beer. These refrigeratin g arrangementsaccording to my experiments are perfectly suitable to answer all justrequirements with respect to refrigeration and can be kept exactly orconstantly regulated to the extent of one-half degree ccntigrade. Thesame are allowed to act day and night, so that in the morning the beerwhich stands immediately behind the plug of the tap is exactly of thesame quality and tastefulness as that whichis contained in the barrel.

\Vhat I claim, and desire to secure by Letters Patent of the UnitedStates, is

1. The combination with the storage-chamber containing the ice-box 70having waterchamber H, of the box 7tabove the said chamber and havingthe superimposed box It, the pipe Z connecting the box 70 with the saidwater-chamber, the coil Win the ice-box having pipe connection Z withthe box it and also connected with the chamber H, and the overflow-pipeZ for the box 7r, substantially as described.

2. In a beer drawing and refrigerating apparatus, the combination withthe storagechamber containing a refrigerating vessel, of the box 7.;having the superimposed ice-box k, a pipe leading from said ice-box 7ato the said refrigerating vessel, the gas vessel B located in the box 7;and connected with a pipe containing mercury, said last-mentioned pipeintersecting the ice-water pipe, and a valve a adapted to regulate theflow of said ice-water, substantially as described.
